Strange, the machine reports MySql version 5! My other 7.4 machines show version MySQL 4!
And it looks like the last change to mysql.ini was in 2007 !
This is a frequently issue with those who have upgrade PHP. I solved making my own smeserver-support rpm. Please, don't flame me, this is the only fix I have found.
SO do we still have to migrate to SME 8 for a stable up to date MySQL/PHP set?
